"The operation could not be completed" when ChronoSync runs backup on APFS HDD

The hard drive does not become read-only with the APFS hard drive format on Mac OS.

The documentation of the feature on ChronoSync's website is as follows:

https://www.econtechnologies.com/chronosync/current.html If using APFS as a source, the "Freeze File System" feature will take a snapshot of the file system before backing it up. The snapshot freezes all the files at the moment the sync/backup runs so there is no possibility of any files being modified, added, or removed during the course of the sync/backup. This guarantees the destination will mirror the source at the exact moment the sync/backup begins. This is even true if the computer is being used at the time the sync/backup is running. Freezing the file system is important because macOS is constantly modifying files, even when you are not actively using them. For example, the Photos app will continuously update and modify your photo library even when you have not used the app. Without freezing, the photo library could get modified before it has been fully copied, potentially leading to a corrupt library on the destination!

It seems to me that Bridge is not interacting well or being fully respectful of the way the APFS format works within the operating system during this feature. I have taken care to disable the freeze file system option until this problem can be resolved.
